Here's a little more I stumbled on about the 1908 Olympics Games, in which lacrosse was an official sport. In the Games, Canada beat England, 14-10, in the only game of the match (South Africa withdrew from competition.). In 1904, Canada beat USA.

Match report (No grammar or structure changes made):

South Africa having withdrawn, the only entries left for the Lacrosse Competition were Canada and the United Kingdom, but quality made up for quantity, and though the game is not yet as well-known as it ought to be on this side of the Atlantic, there was little doubt in the spectators’ minds, after seeing this match, that such graceful, fast, and skilful play would be much more widely and deeply appreciated here than has ever been the case before. Both teams were in splendid condition. It was certainly the best exposition of lacrosse ever given in this country, and, equally certainly, it was the finest effort our own players have yet made against any Canadian team. The English side was by far the strongest ever put into the field.

Special care was taken to keep the ground in as good condition as possible for the match of October 24. The only alteration that might be suggested in future tournaments is that two teams, instead of only one, might be allowed to represent each country.

The Englishmen wore red jerseys, and the Canadians had white trimmed with green, with a maple-leaf on the breast. The ground was hard beneath and slippery above, and a little hail fell after the start; but nothing prevented a very fast display, and the weather, on the whole, was good.

For the first time in the history of Canadian lacrosse a team had been selected from all parts of the Dominion to uphold the honour of the nation al game. The difficulties of the undertaking over so vast an area were necessarily great, and they were augmented by the compulsory amateurism required by the Olympic Council. There are still amateurs in plenty playing in Canada, but their skill is well below the professional standard. Consequently it was not until several trial games had been held that the fifteen players were chosen, and they included members of clubs as far apart as New Westminster and Montreal, a distance of 3,000 miles. Hitherto clubs such as Toronto have sent their teams on tour in this country, and they have generally been labelled “The Canadians”; but the Olympic match at the Stadium was the first encounter between the picked amateurs of the two countries, and as such it marked a distinct epoch in lacrosse. The game itself proved to be one of unusual interest, and it was hailed by a crowd, the large majority of whom had assembled to watch the subsequent football match and knew nothing of lacrosse, with unmistakable signs of approval and enthusiasm. It is impossible that such a game as lacrosse, played in the spirit and with the ability that prevailed here, should not appeal to a sport-loving crowd such as was assembled at the Stadium. The finer points of the game were quickly appreciated, and the brilliant short passing of the Canadians and the fine running and direct attack of’ the Englishmen were abundantly recognised.

Lord Roberts, the Right Hon. A. J. Balfour, Baron and Baroness de Tuyll, Lady Sibyl Grey, Lord and Lady Desborough, and many others were present when the match began, and before its close the Lord Mayor arrived in state. The cheers for Canada when the winning team received from him the Olympic gold medals they had so well earned were loud and long from all parts of the crowded enclosure.

A special set of rules had been prepared in order that the conditions under which the game is played in Canada, the United States, Australia, and England might be assimilated, and the Olympic match saw the goal crease enlarged, with special restrictions that prevented an opponent from entering it ; a white ball was used, slightly heavier than English players are accustomed to and somewhat lighter than Canadians use ; the ground was hemmed in by a canvas wall ; and the time of play was divided into four quarters instead of two halves. These were innovations from an English point of view, but every endeavour had been made by the lacrosse authorities to adopt Canadian views, as some small acknowledgment to a team that had come so far.
The Code of Laws used, which differs from the usual English code, appears in later pages of this Report.

Both teams opened scratchily, and to some extent warily, for with the sides adopting somewhat different formations, both had to work into new situations. Canada was much surer of the ball than England, but her work was slow and soft, very careful and very deliberate. Turnbull obtained the ball from the first face, as he did several others, and Canada at once attacked ; then the ball made a short visit to the other end, and on its return some weak checking on England’s defence enabled Canada to score the first goal in little more than a minute. Double that time was occupied before Johnson made a fine run and passed to Buckland who scored for England. Canada now pressed considerably, and, as the English defences were playing in very uncertain fashion, the score rose. Turnbull scored with a remarkable angle shot, having less than three inches to shoot at, through Scott being out of goal and checking first home in anticipation of a pass to that player. Brennan had a hand in two further points ; one knocked through as the result of a poor stop by Scott and another slipped in after the English goalkeeper had stopped with his mouth. Thus the first “twenty” found Canada leading by five goals to one. The second period was quiet for a time, the Englishmen not having yet recovered from their lethargy. There was little of that movement and athletic activity upon which the team was to rely. However, it was the home team that scored the next point, Jones just finding the inside of one of the posts. A longer game ensued, and only on the approach of half- time were the Canadians able to get through. The second quarter had realised a goal each, and the score stood at six goals to two. The third period was remarkably prolific in scoring, for no fewer than eight points were added to the total. Five of these went to England and three to Canada, so that its conclusion saw England in a better position, and Canada’s lead reduced to nine goals to seven. Hamilton had changed places with Turnbull at centre, and Whitley got the best of the face. Parker-Smith secured from the surrounding scrummage, and with a fine run enabled Jones to score a smart goal. Except that Dutton was the invader, the next game was very similar, and Jones added the finishing touch as before. Then came Canada’s turn, led by the irrepressible Turnbull, who first scored with another fine angle shot, and then ran straight through Parker-Smith and scored with a very low, hard shot. As the direct result of a free throw given against England, the ball was worked behind goal and then whipped through from the lob in front—an old dodge, for which “ check sticks ” used to be the remedy. From now the game veered in England’s favour. The team had gradually been waking up, and now at last played its true game. Rapid passing down the field from crosse to crosse whilst on the run gave Jones and Buckland their chance, and the last-named scored. Parker-Smith was soon away, and similar work enabled Buckland to score again, and then, after a slight rally by Canada, the same player once more got through in most brilliant fashion. Excitement ran high when the last period was started. Canada attacked to begin with, but Alexander, who had followed down, received the ball again from Mason, and some fine work, in which Hayes participated, enabled Jones to tip the ball in at close quarters. The next game was brief, and was taken by England as the result of further good combined work. This score brought the totals level, at nine goals. From here the English play deteriorated, and Canada, led as before by Turnbull, gradually won the match. Turnbull first enabled Brennan to knock through from a lob, and so Canada was one up. Then splendid short passing, in which the whole attack shared, was successful. Turnbull next found himself free near goal, with the inevitable result, and once again Brennan knocked through from a lob behind of Turnbull’s. Hereabouts the English defence had gone to pieces, and so two Canadians were left free in front of goal, and Canada added their last point. England scored once more, which brought the concluding totals to fourteen goals to Canada and ten to England.

A heck of a game from Alex Turnbull. My favorite line from the above: "The game itself proved to be one of unusual interest, and it was hailed by a crowd, the large majority of whom had assembled to watch the subsequent football match and knew nothing of lacrosse, with unmistakable signs of approval and enthusiasm. It is impossible that such a game as lacrosse, played in the spirit and with the ability that prevailed here, should not appeal to a sport-loving crowd such as was assembled at the Stadium."

Another interesting part is the regulations and rules section. You can find this on page 569 of the report, but here are some noteworthy excerpts.

Regulations for 'The Crosse'

The crosse may be of any length. In its widest part it shall not exceed one foot. A string must be brought through a hole at the side of the tip of the turn to prevent the point of the stick catching an opponent's crosse. A leading string resting on the top of the stick may be used. No string may be fastened so as to form a pocket. The length strings shall be woven to within two inches of their termination, so that the ball cannot catch in the meshes. No metal of any kind shall be allowed upon the crosse; splices must be made either with string or gut.

Part V, Section II

Should an accident or injury occur to any player which, in the opinion of the Referee, incapacitates him from playing, the opposing side must withdraw one of their players as long as the player remains so incapacitated. If the “accident” or “injury” is due to a foul, and the Referee suspend the offending player, a player other than the suspended one shall be withdrawn.

The whole document is worth a read just for its historical significance, whether you read about lacrosse or not. Will lacrosse become an Olympic sport? Only time will tell. But for now, we can be excited about the 2014 FIL World Championships, held in Denver. The USA roster for the "Duel in Denver" matchup of Team USA vs. Canada can be found here.
